To all whom it may concern:

Be it known that I, ADOLF FISCHER, a citizen of the. United States, residing at Orangeville, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Compos tion Cork, of which ,the following is a specification.

In the manufacture of various articles from such materials as cork, wood pulp, corn-cob pulp and the like, the shavings, chips, etc.,'are more or less a-waste product, and ordinarily not susceptible of further use except in the manufacture of articles of a very inferior value. The inventlon therefore has for its objectto utilize this waste product in the manufacture of the same articles as originally made-from the materials aforementioned, and more particularly to utilize the waste resulting from the manufacture of bottle stoppers from cork. When bottle stoppers are cut from cork there is left considerable Waste, and the present invention utilizes this waste product for the manufacture of'bottle stoppers,

the same having all the good qualities as stoppers made from ordinary cork.

In carrying out the invention, I first providea glue binder consisting of the following ingredientsin substantially the proportions stated: \Vater 1% pounds, glue (preferably bone marrow glue) 1 pound, glycerine1 pounds, sugar 1 ounce, oil of fir 1 ounce, ammonia ounce, hexamethyleneamine ounce.

These ingredients are boiled together for approximately two hours until a congealed product is obtained which is allowed to cool.

I next take 1 gallon of linseed oil and cook the'same until it thickens, and to this I-add one pound of sulphur. "These two ingredients are thoroughly mixed and then 'permitted to cool, whereupon the mixture'becomes hard and brittle so that it may be grated or otherwise comminuted.

.I then take four parts of groundwaste cork and one-half part ofthe comminuted substance last described, and heat the same to approximately 100 degrees Fahr. and thoroughly .mix these two products, and

while doing so I add three fourths part of the gluesolution hereinbefore described. Before the glue solution is added, it is heated until 1t liquefies so that it may mix more readily. The whole is now heated and thoroughly mixed, and :it is then poured Application flledfieptember 30, 1922. Serial No. 591,649.

into forms or molds and compressed therein. The molded product is next baked at a temperature of 180 to 220 degrees Fahr. until it attains the desired degree of hard- "ness. The composition is now finished and upon removal from the molds it can be cut lntostoppers or other articles. The waste from the composition can be used over and over again without becoming hard and unfit for further use, which is usually the case with the waste cork, Wood pulp and the like as used at the present time.

Groundcork, wood pulp and the like are now utilized by being subjected to various processes, but after going through the process but once they are unfit for further use for the reason that the cork or pulp becomes hardened by the process. However, with the present composition, the waste product from each operation can be used over and over again until entirely .con

to prevent hardening thereof to some ex tent. I Thesugar acts as a coloring matter, 1t imparting a brown color to the finished product during the baking process. Oil of fir is used to deodorize the other ingredients, and ammonia acts to bleach the product. The purpose of the linseed oil and sulphur 1s to keep the finished product soft, the same having the same physical properties as ordlnary cork. a

I claim: A composition of matter consisting of a mixture of cork, linseed oil and sulphur, and a binder, composed of glue mixture containing hexamethyleneamine.

2. A composition of matter consisting of a mlxture of cork, linseed oil and sulphur, and a binder, composed of a glue mixture containing glycerine, sugar, ammonia and hexamethyleneamine.

3. The process of utilizing scrap cork, consisting in comminuting scrap cork, mixmg the same with linseed oil and sulphur,

adding a binder composed of a glue mix- 4. The process of utilizing scrap cork,

consisting in comminuting scrap cork, mixing the same with linseed oil and sulphur,

adding a binder composed of a glue mixture containing glycerine, sugar, ammonia, and hexamethyleneamine to the mixture, and then solidifying the resultant product in molds by the application of heat thereto.

5. The process of utilizing scrap cork con sisting in comminuting scrap cork, mixing the same in a heated state with linseed oil and sulphur, adding a binder composed of a glue mixture containing glycerine, sugar, ammonia, and hexamethyleneamine to the mixture and heating the same, pouring the mixture into molds and solidifying the mixture by the application of heat thereto.

In testimony whereof I afiix my signature.

ADOLF FISCHER.
